The copper strip corrodes test measures the corrosion of Hydrocarbon liquids by the presence of an active ingredient. It's a subjective test comparing the corrosion of a single copper strip with the corrosion and discoloration of a standardized copper coupon on a laboratory test bench. Passing the copper strip corrode test is usually a requirement of hydrocarbon retail sales contracts. These tests are generally performed at the point-of-sale level or in a laboratory environment. For this reason, you must read and understand the test and know the criteria before applying for any hydrocarbon retail sales contract.




A copper strip test is performed to ensure the stability of Hydrocarbon formulations in liquid form. It involves the test of an inert strip of copper sheet with the hydrocarbons contained in a bottle of liquid hydrocarbons. The test measures whether the hydrocarbons in the bottle will bond to the inert strip of copper. In essence, it's an electrochemical test that will measure the electrical conductivity of the hydrocarbon liquid in a specific solution. Passing this test will prove your hydrocarbon retail store sales contract with the retailer. If you fail, you're looking at a rejection of your hydrocarbon retail sales contract. Therefore, you need to understand what the test entails and what to expect from the testing process.


Before the test begins, the liquid is placed in a test container that has a small amount of water. When the hydrocarbons in the bottle come into contact with the surface of the copper strip, the electrical conductivity of the hydrocarbons is measured. The higher the electrical conductivity of the liquid, the greater the bonding strength of the hydrocarbons. Passing this test indicates that the Hydrocarbon liquid is stable, safe and meets the standards that the retailer is looking for in a Hydrocarbon retail sales contract.
